This is a fun thread. I'm sure I could find some more if I look hard enough but I'll include the first 2 that come to mind. Curiously they're both very similar. The first one was taken while I was in a botanical garden manual focusing on flowers with the lens near minimum focus distance set and happened to look in the other direction but without time to change anything. Even so I guess I have to admit that I still like the photo. In the second photo, I was just too close with the wrong lens that took too long to focus.
